Assessment of soil arsenic (As) bioavailability may profoundly affect the extent remediation required at contaminated sites by improving human exposure estimates. Because small adjustments in As estimates can significantly alter risk assessments and goals, convenient, rapid, reliable, inexpensive tools are needed to determine bioavailability.We evaluated methods for assessing as a means improve potentially reduce costs.Nine soils from residential affected mining or smelting activity two...
Serum concentrations of PBDEs were measured using gas chromatography-tandem mass spectrometry in 80 children aged 15-71 months. Demographic and behavioral data collected on parental questionnaires; a research nurse recorded anthropometric measures insurance status. For subset (n = 17), house dust child handwipes sampled during home visit. In linear Tobit regression, log-transformed PBDE congeners modeled as function characteristics, including neighborhood-level socioeconomic indicators. BDE...
Snus is an oral tobacco product that originated in Sweden. products are available as fine-cut loose or pre-portioned porous "pouches." Some snus undergo pasteurization during manufacturing, a process removes reduces nitrite-forming microbes, resulting less tobacco-specific nitrosamine content the product. companies and researchers have suggested potentially harmful than traditional thus potential smoking cessation aid alternative to continued cigarette consumption. Although various...
Waste collection services are uncommon in rural areas of low-resource countries, causing waste accumulation and subsequent dumping burning garbage. Air pollution from household garbage burning, including plastics, has been observed Jalapa, Guatemala addition to air (HAP) cooking. Adolescent girls often help with these cooking tasks, but little is known about their exposures. We characterized 24-h exposures HAP adolescent by measuring fine particulate matter (PM2.5), black carbon (BC),...
Smokeless tobacco (ST) products are widely used throughout the world and contribute to morbidity mortality in users through an increased risk of cancers oral diseases. Bacterial populations ST taste, but their presence can also create carcinogenic, Tobacco-Specific N-nitrosamines (TSNAs). Previous studies microbial communities lacked chemistry data (e.g. nicotine, TSNAs) characterize identify associations between carcinogen levels taxonomic groups. This study uses statistical analysis...
In recent years, methods like spectroscopy have emerged as a viable option to accurately measure underwater concentrations of nitrate. Excessive nitrate levels in bodies water cause environmental concerns, such eutrophication. As such, the role accurate and responsive sensors became significant artificially maintaining optimal level. Conventional techniques are costly, so monitoring wide region lake is impractical. To address aforementioned issue, we propose cost-effective biosensor...
